LaRocque contributed a guitar solo to the track "Cold", featured on the album Slaughter of the Soul by Swedish melodic death metal group At the Gates. Producer Fredrik Nordström was responsible for the idea, and telephoned LaRocque. At the Gates' guitarist Anders Björler gave LaRocque an audio cassette recording of the song. The tape played at the wrong speed at LaRocque's house, so LaRocque had to transcribe the recording. Two days after receiving the cassette, LaRocque laid down a guitar solo for the song within half an hour. Björler described the solo as "great" and in a November 2007 interview admitted he still couldn't play the solo "properly".
He owns a studio called the "Los Angered Recordings" in Angered, Sweden, since 1995, where he records many albums of other bands. In 2007, Andy moved the studio to Varberg and renamed the studio to "Sonic Train Studios" where he keeps producing bands to this date.
He is well known for his signature guitar style incorporating neoclassical elements into his playing, specially by using exotic scales such as harmonic minor, phrygiant dominant, diminished minor scale. His extended theory knowledge makes him able to mix these neo-classical scales with other ones such as blues scale or melodic minor. He has a very distinct guitar tone for his solos, and often incorporates layers of harmonies over his scale runs and phrasing. He frequently uses a mixture of classically flavored arpeggio sequences and alternate picked scale runs intermixed with melody lines to create his signature style. He cites Michael Schenker and Randy Rhoads as major influences. He also likes Steve Vai, Tony Iommi, and was impressed by the playing of Chuck Schuldiner when he recorded "Individual Thought Patterns" with him.
